Abstract
Drilling system and methods may employ a weight-on-bit optimization for an existing drilling mode and, upon transitioning to a different drilling mode, determine an initial weight-on-bit within a range derived from: a sinusoidal buckling ratio, a helical buckling ratio, and the weight-on-bit value for the prior drilling mode. The sinusoidal buckling ratio is the ratio of a minimum weight-on-bit to induce sinusoidal buckling in a sliding mode to a minimum weight-on-bit to induce sinusoidal buckling in a rotating mode, and the helical buckling ratio is the ratio of a minimum weight-on-bit to induce helical buckling in the sliding mode to a minimum weight-on-bit to induce helical buckling in the rotating mode. The ratios are a function of the length of the drill string and hence vary with the position of the drill bit along the borehole.
Description
Background technology
Modern drilling operation has become the miracle in technology and engineering science. Industry is to maximize profitability to have doneMake great efforts to relate to " nonproductive time " from minimize on one's own initiative rig and staff during drilling process and maximize and creep intoSpeed so that exploitation are for maximizing the new method of reservoir drainage rates and throughput rate. For drilling crew commonly at presentHandle its drill string along selecting the preplanned or adaptively selected drilling track of placing for the best.
In the degree of staff's maximizing rate of penetration (can not cause extra nonproductive time), staffCan complete quickly boring and therefore in given budgetary more boring that completes. Affect one of principal element of rate of penetration (to the greatest extentPipe unique factor by no means) be the pressure of the drill. The pressure of the drill is the big or small measurement that drill string is applied to the power in bit face. Described the pressure of the drill be withThe function of lower: the configuration (size and the number that comprise heavy rigidity jumping through rings) of shaft bottom drill tool assembly, the weight of drill string itselfWith rigidity, hook load (lifting force on the upper end of drill string), boring size and track and comprise the multiple moving of frictional forceState factor. As below further set forth, these dynamic factors are subject to the impact of drilling model.
Rate of penetration is not the monotonic function of the pressure of the drill. Have one " available point ", the pressure of the drill increase is exceeded described " to be had mostEffect point " in fact can reduce rate of penetration and finally cause wearing and tearing too early and the damage to drill bit. Similarly, the pressure of the drill is not largeThe monotonic function of hook load. In the time that hook load reduces, drill string arrives shaft bottom drill tool assembly by its weight transmitting at first, increases thusThe pressure of the drill. But, in the time that hook load further reduces, can cause drill stem buckling along the axial load of drill string, thereby increase drill stringAnd the friction between wall. In addition, axial load causes Tubing Buckling and finally reaches the state that is called " locking ", at described stateUnder, frictional force stops along any being advanced further of boring.
This complex nature of the problem causes the exploitation for several different methods and the technology of optimizing drilling speed. But, this multiplePolygamy increases during guiding process. Particularly, as a part for guiding process, staff conventionally need to be at drilling well mouldBetween formula, change. For example, in the time keeping the current route of drill bit, adopt the staff of bent sub guiding technique " revolvingRotary-die type " lower operation, drill string rotating in described rotary mode. In order to depart from current route, staff is converted to " sliding dieFormula ", in described sliding-modes, the rotation of drill string is stopped. (owing to there being down-hole motor, drill bit continues rotation. ) conventionally needBetween two patterns, often change back and forth. Regrettably, due to differentiated friction power and different flexing threshold value, therefore different modeThere is Different Weight transfer characteristic. Existing method and technology seem to take into account fully these differences, and people therefore worksMember must exceedingly limit its rate of penetration during guiding process.

Detailed description of the invention
Some disclosed system and method embodiment adopts rate of penetration optimization for existing drilling model, and is turningAfter changing to different drilling models, Sine Buckling ratio, Helical Buckling ratio and the pressure of the drill value based on previous drilling model are determinedCorresponding the pressure of the drill scope. Sine Buckling than be minimum the pressure of the drill for bring out Sine Buckling at sliding-modes with at rotating mouldIn formula, bring out the ratio of minimum the pressure of the drill of Sine Buckling, and Helical Buckling ratio is for bringing out Helical Buckling at sliding-modesMinimum the pressure of the drill with for bring out the ratio of minimum the pressure of the drill of Helical Buckling at rotary mode. Described ratio is drill string lengthFunction, therefore changes along the change in location of boring with drill bit. Configuration that other factors comprises drill string (weight, rigidity, diameter,Coefficient of friction), boring size and drilling track.
Before starting any further optimization of rate of penetration, the pressure of the drill of current drilling model is transformed into specified scope(or equivalently, the ratio between current the pressure of the drill and previous the pressure of the drill is transformed into the model between Sine Buckling ratio and Helical Buckling ratioEnclose). In this way, can repeatedly carry out as required the transformation between sliding-modes and rotary mode and can not increase flexing andLock risk and during guiding process, can excessively not damage rate of penetration.
Fig. 1 illustrates illustrative well system, and described well system has the drilling platforms 2 with derrick 4, and described drilling well is flatPlatform has the travelling block 6 for rising and fall drill string 8. In the time that drill string 8 declines through well head 12, top drive 10 supportsDrill string and make alternatively drill string rotating. Drill bit 14 is by the rotary actuation of down-hole motor and/or drill string 8. In the time that drill bit 14 rotates, boreCapitiform becomes the boring 16 through various stratum. Pump 18 circulates through feed pipe 22 drilling fluid 20, arrives through the inside of drill string 8Reach drill bit 14. Fluid flows out the aperture in drill bit 14 and upwards flows through drill string 8 annular space around so that drilling cuttings is sent to ground, itsMiddle fluid filters and recycles.
Drill bit 14 is only of shaft bottom drill tool assembly 24, shaft bottom drill tool assembly comprise down-hole motor and provide weight andRigidity is to assist one or more " jumping through rings " (thick walled steel tube) of drilling process. Conventionally, some jumping through rings in these jumping through rings compriseBuilt-in logging instrument, it is for collecting the such as measured value of each drilling parameter of position, orientation, the pressure of the drill, bore diameter etc. Can rootSpecify tool orientation, described tool face azimuth, inclination angle according to tool face azimuth (direction of rotation), inclination angle (slope) and compass headingAnd each in compass heading can obtain from the measured value of magnetometer, inclinometer and/or accelerometer, although alternatelyUse for example gyrostatic other sensor type. In a specific embodiments, described kit is containing three axis fluxgate magneticPower meter and triaxial accelerometer. As known in the state of the art, the combination implementation tool face angle of these two sensing systems, inclination angle andThe measurement of compass heading. Described orientation survey can be with gyroscope survey or IMU with tracer tools position exactly.
Remote measurement joint is also contained in shaft bottom drill tool assembly 24, and it keeps the communication linkage with ground. Mud-pulse telemetryTechnology is for tool measurements being delivered to geoceiver and receiving the common telemetry of one of order from ground, butAlso to use other telemetry. For example, for some technology (, acoustic signal transmission through walls), drill string 8 comprise for detection of,Amplification and again one or more repeaters 30 of signal transmission. At ground place, converter 28 is in mechanical type and electric formBetween switching signal, thereby make Network Interface Module 36 from remote measurement joint, receive upward signal and (at least at someIn embodiment) downstream signal is transferred to remote measurement joint. Data handling system 50 receives described in digital telemetering signal, demodulation to be believedNumber and to user's show tools data or well log. Software (being expressed as information storage medium 52 in Fig. 1) control system 50Operation. User via one or more input units 54 and one or more output device 56 and system 50 with and software 52Alternately. In some system implementation plans, driller adopts described system to make geosteering decision-making and by suitable commandsBe sent to shaft bottom drill tool assembly 24.
Based on the output of data handling system, driller can further adjust the operation of travelling block 6 on demand to regulateHook load and the pressure of the drill. Some advanced boring tower configurations make data handling system can automatically carry out this operation, to maximizeBe vulnerable to the rate of penetration of multiple restriction. For example, can apply some the pressure of the drill by data handling system 50 limits to prevent drill bitOr boring tower cause damage, guarantee drilling cuttings from boring, fully rinse out, under balance pressure drilling or present blowout dangerous andAvoid being in other situation of any type of locking (comprising Helical Buckling) and ensure the sufficient response time.
As previously mentioned, drill string experiences flexing under the axial load increasing. Fig. 2 A illustrates and is commonly referred to " sinusoidal bendingBent " first kind flexing. Suppose horizontal drilling, as drill string 202 shown at end-view is settled along the bottom side of boring, but from bowingIn view, can see, drill string has presented and has been similar to sinusoidal waveform. (ripple week for illustration purposes under this appropriate flexionPhase property is exaggerated in the drawings) frictional force and power transmission too not different with frictional force and the power transmission of straight drill string, therefore thisPlant initial flexion and be conventionally regarded as acceptable operating condition. But along with axial load increases, wave amplitude increases and the cycleReduce, until buckling pattern is converted to " spiral " buckling pattern shown in Fig. 2 B. The same with gimlet, drill string 204 presents spiral shellRevolve shape and apply large power to the wall of a borehole. Frictional force becomes main, thereby is suppressed to any power transmission of shaft bottom drill tool assembly.Known this flexion efficiency risk very low, that damage drill string raises and is conventionally regarded as unacceptable operating condition. Can lead toIn the scope of being everlasting between these two states, find to provide the operating condition of maximum the pressure of the drill.
Fig. 3 illustrates the illustrative boring method that adopts the pattern based on ratio to switch. Described boring method can be by multipleMode is implemented, and is included in data handling system 50 and is embodied as software. Start from frame 302, the ongoing drilling well behaviour of system monitoringDo, thereby collect rotating speed per minute and the drilling track of indicating (inter alia) the pressure of the drill, hook load, moment of torsion, drill stringMeasured value. The combination of these measured values can be used for obtaining the mode of operation of drill string and estimating threshold value, and described threshold value for example, canThere is minimum the pressure of the drill of Sine Buckling and can occur minimum the pressure of the drill of Helical Buckling. Can find in the literature for these calculatingModel. Referring to, for example, He and Kyllingstad " for Helical Buckling and the locking bar of the coiled tubing of crooked holePart ", SPE drilling and completion technology, the 10th to 15 pages, March nineteen ninety-five. These calculating also can be carried out by commercially available software, for example, and canDecision space well engineering (DSWE) bag of buying to Halliburton.
In frame 304, systems inspection is the institute of the drilling model of (or vice versa) from rotary mode to sliding-modes for exampleNeed to change. In the situation that not there is not transformation, system estimation and show optimum weight on bit value and turn back to frame 302 in frame 306.Otherwise if start to be converted to present mode from preceding mode, in frame 308, system discovery is for current bit locationSine and Helical Buckling ratio. Sine Buckling than be minimum the pressure of the drill for bring out Sine Buckling at sliding-modes with for revolvingIn rotary-die type, bring out the ratio of minimum the pressure of the drill of Sine Buckling, and Helical Buckling ratio is for bringing out spiral at sliding-modesMinimum the pressure of the drill of flexing with for bring out the ratio of minimum the pressure of the drill of Helical Buckling at rotary mode. These the pressure of the drill value and ratiosDepend on multiple factors, the local path of drill string weight, drill string stiffness and the boring that comprises per unit length.
Temporarily turn to Fig. 4, illustrative ratio is illustrated as the function of drill string length (taking foot as unit). Curve 402 illustratesSine Buckling ratio, and curve 404 illustrates Helical Buckling ratio. Sine Buckling is than dropping to approximately from approximately 0.154 of 15,000 feet of placesZero of 18,900 feet of places. Helical Buckling is than dropping to approximately 0.025 of 20,000 feet of places from approximately 0.21 of 15,000 feet of places.Described curve is not dull, because two ratios of the interim increase of the hole deviation of approximately 17,600 feet. Curve is used to specify requiredAction pane 406,408, fixes for the boring of 200 feet of length at action pane described in illustrative example. Specifically, it should be noted that during guiding process, action required window 408 is shown significantly to be increased, thereby realizes the brill of attempting than in the pastThe drilling speed that speed is higher. At least some embodiments of data handling system 50 can be used the chart that is similar to Fig. 4 to provide to userDrilling well window is visual.
Return to Fig. 3, in frame 310, system determines whether drilling model transformation makes the pressure of the drill reduce. To subtract for the pressure of the drillLittle transformation, reduces to avoid exceeding the Helical Buckling threshold value reducing described in should carrying out before changing. Some this reducing canFriction by the increase that drill string stands in the time that drill string is converted to present mode from preceding mode causes, but also may need to adjustHook load. Described adjustment should be timed to avoid to apply in the time having realized current drilling model too much axial load. Therefore,Reduce for the pressure of the drill, be converted to present mode (in frame 314) before system carry out necessary the pressure of the drill adjustment (at frame 312In). Initial the pressure of the drill of current drilling model should fall in suitable action required window, and described action pane is in disclosed realityExecute in scheme and recently define according to Sine Buckling ratio and Helical Buckling.
In some embodiments of frame 312, the optimum weight on bit of preceding mode is (as afoot operation in frame 306Determine during this time) combine to determine the pressure of the drill limit value of action required window with flexing ratio. Adjust on demand subsequently present modeInitial the pressure of the drill to operate in this window. After this, system can turn back to frame 302 and adopt common optimum strategy to improve currentThe pressure of the drill value of drilling model.
In other embodiments, system is according to determining the pressure of the drill value of expection to the transformation of present mode and calculating thisThe ratio of the optimum weight on bit value (as previously determined in frame 306) of value and preceding mode. (this desired value sliding-modes of can serving as reasonsThe result of the change in friction force that causes of transformation). This pressure of the drill ratio is compared to determine that with sinusoidal and Helical Buckling ratio system isNo will operation in required window. If needed, adjust initial the pressure of the drill of present mode may pass through to change hook loadMake described the pressure of the drill ratio be positioned at window. After this, system can turn back to frame 302 and adopt common optimum strategy to improve current behaviourThe pressure of the drill value of doing.
For the transformation that needs the pressure of the drill to increase, should before increasing the pressure of the drill, start to be converted to present mode to avoid previouslyIn pattern, apply excessive axial load. The friction reducing that some increases can be stood by the drill string in present mode causes, butAlso may need to adjust hook load. Described adjustment should be timed to avoid to apply before starting present mode too much axiallyLoad. Therefore, carrying out necessary the pressure of the drill adjustment (in frame 318) before, system starts to be switched to and to work as front mould from preceding modeFormula (in frame 316). As discussed previously, based on previous the pressure of the drill and sinusoidal and Helical Buckling than defining at the beginning of rotary modeThe action required window of beginning the pressure of the drill. The same with previous embodiment, window can by ratio itself represent and with expect the pressure of the drill valueCompare with the ratio of previous the pressure of the drill value, or be alternatively expressed as by previous the pressure of the drill value and flexing ratio are combined to determined the pressure of the drillValue. After setting initial the pressure of the drill of rotary mode, system turns back to frame 302.
